Mankind try to replace oil-based plastics by so-called biodegradable bioplastics to minimize plastic pollution. These bioplastics requires specific conditions for biodegradation, which are usually not met in nature. This could lead to formation of microplastic debris “Micro-bioplastics”. There are plenty of analytical methods for determination of conventional microplastic presence or concentration in aquatic systems, the less of studies focus on analysis in soils due complexity of this matrix and there is lack of methods for determination of micro-bioplastics. The most difficult, time consuming and dangerous for analyte are soil sample pre-treatment and preconcentration or extraction of bioplastics. That’s why we have developed direct analytical method using evolved gas analysis (EGA, combination of thermal degradation and mass spectrometry) for determination of micro-bioplastics, which does not require any of these sample preparation techniques. We present data on use this method for determination of micro-bioplastics in Siberian and Czech soils, the standard Lufa soil and in sewage sludge. Application of this method was already successfully demonstrated for determination oil-based microplastics. In this work, as a model bioplastic was used polyhydroxybutyrate (PHB) and polylactic acid (PLA). We demonstrate a fast, robust, and easy EGA method for determination of PHB and PLA micro-bioplastics in soil and other solid matrix with possible differentiation of anthropogenic PHB from natural PHB. In addition, this method could be helpful for verification and precising of biodegradation tests and contamination evaluation of soil after applying micro-bioplastic polluted compost.
